With the new revised version achieving an overalll DxOMark score of 21 points, the Sony mount version performs very well, although not quite achieving the same high scores when compared to the VC version when fitted to either the Canon EOS 5D Mk III or the Nikon D800. In terms of Sharpness scores the Sony combination matches the Canon but Transmission is lower at 3.1T vs 2.8T while Distortion levels are very slightly higher. The Nikon duo achieves higher Sharpness scores (17P-Mpix), and has slightly lower levels of Distortion but the Sony pair have marginally lower chromatic aberration.
